dependency from the dependency graph.

Updates:

- github.com/Azure/go-autorest/autorest v0.11.24: https://github.com/Azure/go-autorest/compare/autorest/v0.11.20...autorest/v0.11.24
- github.com/Azure/go-autorest/autorest/adal v0.9.18: https://github.com/Azure/go-autorest/compare/autorest/adal/v0.9.15...autorest/adal/v0.9.18
- github.com/golang-jwt/jwt v4.2.0: https://github.com/golang-jwt/jwt/compare/v4.0.0...v4.2.0

Before this:

    go mod graph | grep 'jwt'
    github.com/Azure/go-autorest/autorest/adal@v0.9.15 github.com/golang-jwt/jwt/v4@v4.0.0
    github.com/Azure/go-autorest/autorest/adal@v0.9.13 github.com/form3tech-oss/jwt-go@v3.2.2+incompatible

After this:

    go mod graph | grep 'jwt'
    github.com/Azure/go-autorest/autorest@v0.11.24 github.com/golang-jwt/jwt/v4@v4.2.0
